You don't actually know what HDR is, do you? It has nothing to do with resolution.
To vastly oversimplify it, HDR images and videos have the ability to store colors that are brighter and more vibrant what a normal SDR image or video can store, which can then be displayed on an HDR display.

Because it's SDR.
It's just meant to approximate what HDR WOULD look like if you could somehow change the exposure level of your eyes.

No? That photo is just at a lower exposure.
Though HDR, in its purest form, is just "brighter colors". One of the things I did before I had a proper HDR screen is that I would make SDR versions of my projects, rendered at a lower exposure, then send them to my OLED phone, put the brightness up way high, and display the image. This was a good way to "fake" HDR.
...Though I can't say I fancied exiting the image and being blinded by a searingly bright UI. I much prefer working in actual HDR, where the image can get bright but the UI stays at a reasonable level.

You're not seeing HDR, though. You're seeing an approximation made to work in SDR. In real life, the midtones would be of similar brightness to the first frame, but the difference in brightness between the SDR and HDR displays would be compatible to the second or third frames.

Kinda. You need those experimental Vulkan drivers, or the Mesa 25.1 drivers, an HDR-capable display server (Wayland), and an HDR-enabled compositor (Plasma 6.x or GNOME 48 and above). And even then it's only really MPV and video games that have HDR support at the moment.

Most people probably don't even know what HDR actually is, and marketers do a terrible job at explaining it.
